Monks meets the Bumbles and purchases a locket that Mrs. Bumble redeemed with a pawn ticket that she took away from the dead Sally, who had received the pledge from Oliver's dying mother. The trinket contains a ring inscribed with the name "Agnes"; Monks drops it into the river.
Nancy, who sympathizes with Oliver, nurses Sikes until he regains his "natural" meanness. She drugs the man and slips away to Hyde Park for a secret meeting with Rose Maylie. Nancy tells Miss Maylie everything that she has learned by eavesdropping on Fagin and Monks on two occasions. The two rogues are plotting the destruction of the object of Monks's inveterate hatred — his brother Oliver. Mr. Brownlow, who has been absent from London, reappears and Rose tells him Nancy's story. Harry Maylie, Grimwig, and Mr. Losberne are also briefed on what Nancy has learned.
Noah Claypole and Charlotte, Sowerberry's maidservant, hide out in London after she has plundered the undertaker's till. They are discovered by Fagin, and Noah is employed to visit the police station to bring back information about the Dodger's indictment as a pickpocket. Because of her suspicious behavior, Fagin then assigns the sneak to spy on her. Nancy has a midnight meeting with Rose and Brownlow on London Bridge. Nancy informs Brownlow how he can corner Monks. Noah hears everything and immediately reports his findings to Fagin.
Fagin waits up for the marauding Sikes and provokingly discloses Nancy's double-dealing. Sikes promptly goes home and bludgeons her to death. After wandering in the country for a day, haunted by his evil deed, the murderer returns to London.
